Abstract: Abstract of the Disclosure Apparatus for use in combination with an inductive loop for detect-ing metal objects, e.g. vehicles, in the immediate vicinity of said loop. The loop may, for example, be a coil of wire buried in a roadway in a plane parallel to the roadway surface.  Oscillator circuitry is operatively con-nected to the loop with the frequency of oscillation being determined by the loop inductance, which in turn is dependent on whether or not the vehicle is over the loop.  The loop frequency is monitored by digital circuitry in-cluding a loop counter which counts loop oscillator cycles and a duration counter which measures the time duration of a fixed number of loop oscillator cycles.  The measured time duration is compared with an adaptable reference duration to ascertain whether the loop oscillator frequency has increased or decreased.  The presence of a vehicle over the loop decreases loop in-ductance, increases loop frequency, and thus reduces the measured time duration of a fixed number of loop cycles.  A reduction in the measured time duration by an amount greater than a preselected threshold value produces an output signal or "call" to indicate the vehicle's presence.
